What to look for in a GM OBD2 scanner app
A GM scanner app setup has two parts: the vehicle interface that connects to the OBD port and the phone, tablet, or computer software that displays the information. That distinction matters because a low-cost adapter may only provide engine data through a separate app, while a GM-focused system may access modules such as the ABS, SRS, transmission, body control module, battery system, or tire pressure system.
Start with your vehicle and the fault you need to investigate. Standard OBD2 functions can retrieve powertrain codes, freeze-frame information, live data, and inspection readiness information. Those functions are useful for a check engine light, but they do not automatically provide access to non-engine modules or maintenance procedures.
GM coverage also varies by model year and protocol. The manufacturer lists the KINGBOLEN Soloscan for GM OBD2 Scanner Bluetooth as supporting GM vehicles after 1996, but notes that it does not currently support 2011 and newer GM vehicles that require CAN FD. The ANCEL DS500BT Bidirectional Scan Tool specifically lists CAN FD support, which may make it a better starting point for owners of compatible newer vehicles. Even then, the manufacturer says function availability depends on the vehicle, year, and system configuration.
Phone compatibility is another dividing line. Some adapters are designed for iOS, Android, and Windows, while others require a particular application and a network connection. A product that communicates with a phone is not necessarily a complete GM service tool. Confirm the required app, operating system, vehicle year, and intended function before purchase.

CarTechTalk may earn a commission from qualifying purchases made through links on this page. That does not change the compatibility cautions or the reasons to avoid a product.
Best GM focused phone setup: KINGBOLEN Soloscan for GM OBD2 Scanner Bluetooth
The manufacturer lists this adapter as a GM focused Bluetooth scanner that works with the EDIAG application on iOS and Android phones. It is intended for Buick, Chevrolet, Cadillac, GMC, Ravon, Pontiac, Saturn, Holden, Daewoo, and Workhorse vehicles after 1996. Beyond standard OBD2 functions, the listed GM features include full system diagnosis, multiple reset services, and bidirectional control for supported systems.
That combination makes it the clearest fit for a GM owner who wants phone access without committing to a separate handheld tablet. The manufacturer lists functions such as oil, battery, steering angle, transmission, tire pressure, and electronic parking brake resets, but also says special functions vary by model and year. The EDIAG application requires a network connection, and the scanner is not compatible with tablets according to the listing.
Listed price: $79.99. Best for: GM owners who want broad vehicle access through an iOS or Android phone. Drawback: The manufacturer excludes 2011 and newer GM vehicles requiring CAN FD and requires network access for operation. Avoid if: You need tablet support, work primarily on newer CAN FD GM vehicles, or want a completely offline tool.
Best multi brand app adapter: OBDLink MX+ OBD2 Scanner for iPhone
The OBDLink MX+ is the strongest choice for someone who owns a GM vehicle but also wants an adapter that can work with several diagnostic applications and other vehicle brands. The manufacturer lists compatibility with iPhone, Android devices, and Windows PCs, along with enhanced OEM support for GM, Ford, Mazda, Nissan and Infiniti, Toyota and Lexus, Honda, Hyundai, and Kia.
Its listed application support includes FORScan, Torque, BimmerCode, DashCommand, AlfaOBD, and Carista. The manufacturer also lists access to more live parameters than basic scanners, including ABS, SRS, and TPMS data, although the compatibility guide should be checked for the specific vehicle and application. Included firmware updates, over-voltage protection, and battery drain protection are useful ownership considerations for an adapter that may remain connected during diagnosis.
Listed price: $139.95. Best for: GM owners who want one Bluetooth interface for several apps and vehicle brands. Drawback: The listing directs buyers to a compatibility guide because features vary by vehicle and software. Avoid if: You want a dedicated GM menu with guaranteed access to a particular reset or active function without checking application and vehicle support first.
Best lower cost GM handheld alternative: AUTOPHIX 7210P+ OBD2 Scanner for GM with All Reset
The AUTOPHIX 7210P+ is not a phone app adapter, but it is relevant for GM owners who want a more self-contained tool. The manufacturer lists deep scans for GM vehicles, including the engine, transmission, ABS, airbags, body control module, electric power steering, steering angle sensor, air conditioning, radio, parking brake, and fuel pump systems.
It also lists multiple service functions, including oil, electronic parking brake, tire pressure, battery, steering angle, ABS bleeding, gearbox adaptation, and injector coding. The stated GM coverage is most specific for vehicles from 1996 through 2020, with select models from 2020 through 2025. The listing says to confirm compatibility because functions vary by model.
Listed price: $119.99. Best for: DIY owners who prefer a dedicated GM scanner and need service functions beyond engine codes. Drawback: It does not provide the phone app workflow that defines the primary buying intent, and newer model coverage is selective. Avoid if: Your priority is diagnosing from an iPhone or Android device, or you need a specific function that has not been confirmed for your VIN.
Best dedicated screen and active controls: LAUNCH Creader Elite X500 for GM OBD2 Scanner
The LAUNCH Creader Elite X500 is another handheld option for buyers who do not want to depend on a phone. The manufacturer lists a 4-inch touchscreen, Android 8.1, 2GB of memory, 64GB of storage, a 3000mAh battery, full system diagnostics, live data, automatic VIN identification, and active controls for supported GM vehicles from 2006 onward.
Listed service functions include oil, electronic parking brake, steering angle, ABS bleeding, throttle relearn, transmission, tire pressure, battery, injector, and gear resets. The tool supports Wi-Fi updates and can display live data in text, graph, analog gauge, or digital formats. It also lists standard OBD2 functions for compatible vehicles from 1996 onward.
Listed price: $189.99. Best for: GM owners or technicians who want a standalone display and active controls. Drawback: Its full GM auto-scan and one-touch VIN features are listed for 2006 and newer GM models, while functions still vary by model and year. Avoid if: You specifically want a lightweight phone-based scanner or own an older GM vehicle that needs confirmed coverage outside the listed range.
Best for battery information: FOXWELL NT510 Pro fit for GM Scan Tool
The FOXWELL NT510 Pro stands apart by combining GM diagnostics with a 12-volt battery tester. The manufacturer lists battery state of health, state of charge, starting performance, charging performance, and real-time voltage information. For owners troubleshooting no-start complaints or charging concerns, that combination may be more useful than an adapter that only communicates with an app.
GM features include full system diagnostics, bidirectional control, automatic VIN recognition, lifetime updates, and more than 20 reset services. The manufacturer specifically lists crankshaft relearning, electronic parking brake reset, oil reset, airbag warning light reset, throttle body relearning, and ABS bleeding. It says the tool covers 1996 through 2025 Chevrolet, Buick, Cadillac, and GMC vehicles, but requires confirmation because compatibility varies.
Listed price: $235.99. Best for: GM owners who want battery and charging information alongside module diagnostics. Drawback: It is a dedicated scanner rather than an app-first phone interface, and the manufacturer instructs users to update the software on first startup to address earlier lag. Avoid if: You only need inexpensive engine-code access or want diagnostics displayed exclusively on a phone.
Best advanced option for newer compatible vehicles: ANCEL DS500BT Bidirectional Scan Tool
The ANCEL DS500BT is the highest-priced option here and is aimed at serious DIY users, mobile mechanics, and small shops. The manufacturer lists a 7-inch Android tablet, a Bluetooth 5.0 vehicle interface, full system diagnostics, CAN FD support, more than 3,000 active tests, and more than 28 service functions.
Its listed functions include oil, electronic parking brake, steering angle, battery, ABS bleeding, diesel particulate filter regeneration, throttle relearn, injector coding, gearbox relearn, and tire pressure resets. The tool can save, share, or print reports. CAN FD support is a meaningful differentiator for compatible newer vehicles, but it does not guarantee every GM function. The manufacturer asks buyers to provide the vehicle year, make, model, VIN, and required function for compatibility confirmation.
Listed price: $425.99. Best for: Users who need a broad standalone diagnostic platform, active controls, and possible CAN FD access. Drawback: It costs substantially more than phone adapters and still has vehicle-specific limitations. Avoid if: You only need to read a check engine code, or your vehicle and required procedure have not been confirmed with the manufacturer.
Best basic budget adapter: OBD2 Scanner Bluetooth Wireless Car Diagnostic
The LONAUTO OBD2 Scanner Bluetooth Wireless Car Diagnostic is aimed at basic engine diagnostics through its AutoOBDII application. The manufacturer lists iOS, Android, and Windows support, standard engine code access, live data, freeze-frame information, inspection readiness, and EVAP system status.
The limitations are unusually clear. The manufacturer says this adapter does not support ABS, SRS, electronic parking brake, TPMS, transmission, or reset service functions. It also says the device is not compatible with hybrid, plug-in electric, or fully electric vehicles. That makes it a reasonable low-cost choice for a conventional vehicle owner with a check engine light, but not a substitute for a GM-specific full system tool.
Listed price: $18.99. Best for: Basic engine-code reading on compatible conventional vehicles. Drawback: It excludes many modules and service functions that GM owners may expect from a dedicated scanner. Avoid if: You need ABS, airbag, transmission, TPMS, battery registration, or other non-engine access.
Best for app-guided maintenance information: BLCKTEC 420 Bluetooth OBD2 Scanner Diagnostic Tool
The BLCKTEC 420 is a Bluetooth adapter for iOS and Android with an associated app. The manufacturer lists code reading and clearing, live data, battery and alternator information, code severity levels, maintenance schedules, dealer recalls, technical service bulletins, and RepairPal information. It is listed for OBD2-compliant vehicles from 1996 onward.
This product is more attractive to owners who want contextual information around an engine warning than to users seeking GM module programming or advanced resets. The listing does not establish full GM system coverage, bidirectional control, or specific GM service functions. Those omissions should shape the purchase decision.
Listed price: $39.99. Best for: Drivers who want a phone app with maintenance and repair-reference information. Drawback: The listing does not specify GM-specific full system access or reset coverage. Avoid if: You need verified access to ABS, SRS, body modules, or a particular GM relearn procedure.
Not a scanner app: Hirificing OBD1 Scanner, OBD1 to OBD2 GM Adapter
This product should not be confused with a GM OBD2 scanner or application. The manufacturer describes it as a 12-pin GM OBD1 to 16-pin OBD2 connector cable and explicitly says it is only a cable, not a scanner or diagnostic tool. It may connect an existing OBD2 tool to an older GM vehicle with an OBD1 socket, but it does not provide software, code interpretation, module access, or phone connectivity by itself.
Listed price: $8.99. Best for: Someone who already owns a compatible scanner and needs a physical connector for an older GM OBD1 vehicle. Drawback: It cannot perform diagnostics on its own. Avoid if: You are looking for an app, Bluetooth adapter, or complete scanner.
Which GM scanner app setup fits your situation?
- For a GM-focused phone setup: Choose the KINGBOLEN Soloscan, after confirming the model year and whether CAN FD is required.
- For several vehicle brands and apps: Choose the OBDLink MX+, then verify support in the chosen application.
- For basic engine codes under $50: Consider the LONAUTO or BLCKTEC adapter, with the understanding that their listed functions are narrower than full GM diagnostics.
- For a standalone tool: The AUTOPHIX, LAUNCH, FOXWELL, and ANCEL options avoid dependence on a phone screen, but they do not match the app-first intent as closely.
- For older GM OBD1 vehicles: The Hirificing cable is only an accessory and requires a separate compatible diagnostic tool.
The reader who should not buy anything in this guide is someone who needs confirmed dealer-level programming, security-related procedures, or a specific module operation that is not documented for the exact vehicle identification number. That buyer should look for a professional diagnostic service or a tool whose manufacturer explicitly confirms the required procedure, rather than assuming that Bluetooth connectivity or a long feature list guarantees access.

Final verdict
The KINGBOLEN Soloscan for GM OBD2 Scanner Bluetooth is the best match for the refined search intent because it combines a GM-specific feature set with Bluetooth phone connectivity, iOS and Android support, full system scanning, reset functions, and lifetime updates. Its CAN FD limitation and network requirement are meaningful reasons to choose something else.
For broader app flexibility, the OBDLink MX+ is the safer fit. For a low-cost check engine reader, the LONAUTO and BLCKTEC adapters keep the purchase price down, but their listed coverage does not reach the full GM module and service capability many owners want. Always confirm the vehicle year, protocol, operating system, and exact repair function before relying on any scanner for a diagnosis or maintenance procedure.
